SEMI-INDIRECT-LIGHT ATTACHMENT.

into a semi-indirect light fixture.

An object of my invention is to provide an attachment which is simple and inexpen sive and which will utilize a shade of the present ordinary fixture for obtaining the semi-indirect light eect.

A further object of the invention is to provide an attachment of the class described in which the lamp socket of the fixture is utilized for supporting the attachment.

With the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention' consists in the novel construction, combination and arrangement of parts as herein fully described, illustrated and claimed.

In the accompanying drawings, forming part of the application, similar characters of reference indicate corresponding parts in both views.

Figure 1 is a vertical section through an ordinary suspension transformed into a semi-indirect light by means of my attachment; and Fig. 2 is a modified reflector which can be utilized in connection with my attachment.

Referring to the drawings, 3 represents a reflector of any suitable shape and size which has a central opening t through which a lamp 5 can project to engage a socket 6. The edge of the reflector at the opening is flared to form an exterior neck engageable by screws 7 of the shade-holder 8 carried by the socket 6. Or any other means may be used for securing the reflector to the socket, if no shade-holder is provided thereon. The screws 7 which normally support a shade 9, are caused to disengage the shade, the lamp 5 being removed from the socket; the reflector 3 can then be engaged or connected to the shadeV support S, as shown in Fig. 1.

Mounted adjustably within the reflector 8 is a suspension 10 consisting of a U-shaped member the threaded ends l1 0f which pr0- Specification of Letters Patent.

ject through the reflector as shown. Nuts 12 and 13 are provided on the threaded ends whereby the length of the suspension below the reflector can be varied. The U-shaped suspension 10, at the bottom thereof, has a cup 11 which is co-axial with the reflector, and which cup has a downwardly extended threaded stem 15. Engaging the threaded stem 15 is a retaining cup 16 adapted to encompass the cup 14. The neck of the shade 9 is adapted to fit between the cup 14 and the retaining cup 16 when said shade is placed on the suspension 10. The shade is retained on the suspension by means of a nut 17 threaded on to the stem 15, which clamps the retaining cup 16 and, therefore, the shade, to the suspension 10.

It will be noted that the shade 9 which has been removed from the shade support 8 may be utilized on my attachment as stated, therefore the only new members in my semiindirect light attachment are the reflector 3 and the suspension.

My attachment can be secured to a light fixture whether rigid or flexible, that is, one which is secured direct to the ceiling or one which is suspended from the ceiling by a wire, as the attachment is securable to the shade support carried by the socket. The transformation does not require any special skill, as the only part to be removed is the shade, which can then be attached to the suspension 10 before the suspension is secured to the reflector. After the reflector is attached to the shade support on the socket, the suspension with the shade can be secured to the reflector, after the lamp 5 has been secured to the socket.l Thus, an ordinary light fixture can be quickly and easily trans formed into a semi-indirect light by means of my attachment.

In Fig. 2 a reflector 3 is shown which is of a different form than that in Fig. 1. It is self-evident that various forms of relectors can be used in connection with my attachment.

While I have described the principle of operation, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative andi that such changes may be made as are within the scope of the appended claims.

I claim:

1. In combination with an incandescent lamp socket, a shade holder, a reflector delachably supported by the holder, a translucent shade, a U-shaped suspension supported by the reflector, and means for securing the shade to the suspension to maintain the shade opposite the reflector.

2. In combination with an incandescent lamp socket, a shade holder, a reiector detachably supported by the holder, a. translucent shade, a U-shaped suspension the ends of which project through the reector, means adjustable on the ends of the U securing the same to the reflector, and means for securing the shade to the suspension so that the shade is opposite the reflector.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

PHILIP SIMPSON.
